Question

On her multiple choice math test, 1720 of Lydia's answers are correct. What is the ratio of correct to incorrect answers for Lydia on her test?

Answer 1

Answer: $\frac{17}3}$ or 17:3

Step-by-step explanation:

Since Lydia got 17 out of 20 questions correct, that means she got 3 out of 20 incorrect. To get the ratio of correct (17) to incorrect (3) answers, we can simply divide the two numbers as follows:

$\frac{17}3}$ or 17:3

Since this ratio is already in simplest terms, this is the final answer.
